If the instructions else in QML
I tried this for at least 4 hours, with results very little success. Again, I am doing a calculator application simple rank, which displays the percentage and the letter grade.
in C++, I could do something like
//Calculating grade
cout << "Grade: ";
if (result == 100){
cout << "A+" << endl;
}else if (result < 100 && result >= 90){
cout << "A" << endl;
}else if (result < 90 && result >= 80){
cout << "B" << endl;
}else if (result < 80 && result >= 70){
cout << "C" << endl;
}else if (result < 70 && result >= 60){
cout << "D" << endl;
}else if (result < 60){
cout << "F" << endl;
}
but in the cascades, I can't understand how to replace a text of the label with the conditional statements, as above.
I tried follows him and the analysis errors
// Calculate Percentage
Label {
id: grdCalc
enabled: true
visible: false
text: (inTotal.text / inPossible.text) * 100
}
Label {
id: finalGrade
// custom property to calculate final grade percentage
text: "Percent: " + grdCalc.text + "%"
textStyle.alignment: TextAlignment.Center
textStyle.fontWeight: FontWeight.Bold
textStyle.size: 60.0
layoutProperties: StackLayoutProperties {
horizontalAlignment: HorizontalAlignment.Center
verticalAlignment: VerticalAlignment.Center
}
enabled: true
visible: false
}
Label {
id: letGrade
text: {
if (grdCalc.text == 100) {
text = "A+"
} else if (grdCalc.text >= 90 && grdCalc.text < 100) {
text = "A"
} else if (grdCalc.text >= 80 && grdCalc.text < 90) {
text = "B"
} else if (grdCalc.text >= 70 && grdCalc.text < 80) {
text = "C"
} else if (grdCalc.text >= 60 && grdCalc.text < 70) {
text = "D"
} else if (grdCalc.text < 60) {
text = "F"
}
}
}
is there another method to do this?
Try:
text: (grdCalc.text == 100 ? "A+" : (grdCalc.text >= 90 && grdCalc.text < 100 ? "A" : (grdCalc.text >= 80 && grdCalc.text < 90 ? "B" : (grdCalc.text >= 70 && grdCalc.text < 80 ? "C" : (grdCalc.text >= 60 && grdCalc.text < 70 ? "D" : "F")))))

Problem with the C++ object to qml exponent
Hello, I followed the instructions by Qml and C++ integration but got stuck at a certain time.
Here is my code:
// applicationui.cppPage* ApplicationUI::doLoadPageDetails(){ qmlRegisterType("myHtmlPage", 1, 0, "HtmlPage"); QmlDocument *qml = QmlDocument::create("asset:///PageDetails/PageDetails.qml").parent(this); qml->setContextProperty("app", this); HtmlPage *htmlPage = new HtmlPage(); qml->setContextProperty("htmlPage", htmlPage); htmlPage->setHtml("*some html code*"); This function creates a Page with a container that contains a WebView. Here, I want to fill the string saved as htmlPage.html.
I created the RPC classes as described in the link and they work. When I check the htmlPage-> html() in C++, I get the string I wanted.
Now, my problem is how to get this string for qml.
Here's what I do:
import myHtmlPage 1.0....Container { .... ScrollView { visible: true WebView { attachedObjects: [ HtmlPage { id: htmlPage } ] id: webViewScrollable1.... html: "" + "" + "*style options*" + "" + htmlPage.html + //<----- this should give me the string I saved in C++ under htmlPage->html() "" + "" } }But nothing is displayed on the page. But why? I forgot to link something?
I think you're getting confused in the difference between a property and recording a QML component.
You do both.
When you attach an object to a QML file, you create an instantiation of the object at this time, when you set a context property that you you already created that object and are just passing a reference to this.
So when you join HtmlPage in your QML file you create a new object and does not reference that you have created in your program C++ part, so no text.

Using a HP Photosmart Plus B210a printer, I tried to print pictures and emails from my iPhone 4 via the WIFI interface. My router is a Motorola SURFBoard SBG6580. All connections were tested and verified working. The printer is displayed on my iPhone as active, and following my directive to print messages indicate 'contact', 'preparation' and 'printing 1 of 2', etc. Then nothing. No printing. I followed the instructions in the HP troubleshooting for "Apple AirPrint: The Apple Mobile device shows a Job is printing but the printer does not Print", without success. I am able to print from my HP Pavilion Entertainment PC with Windows 7 using the same interface WIFI without problem.
The Motorola router is a recent addition to my system. My unsuccessful resolution of this problem has been to publish a message to see if anyone else following HP Quick has addressed this problem. Thanks for your comments.
An additional step that you could try to do is to do a hard reset on the iPhone. Make sure you that if you have something open that has not been saved first record you these items.
Hold power and home together for 15 seconds button. You can see slide to turn off the screen lights up but ignore that and continue at length on the keys until the unit turns off. Depending on the exact model unit may automatically turn on when let you go and show the apple logo, or you have to manually turn it back on with the power button.
After the device upward charge, try printing again.

Hello
It is a simplified version of my request.
I'm doing 4 things here,
1. the County A.M_ID
2 County has separate .M_ID, is where I have a problem.
3 and 4. It is just the sum of 2 diff columns.
Note that the dates for the County and the amt are different and I can't hard-code the.
Can someone help me step of distinct count?
This query runs also a bit slow.
So all suggestions, comments are welcome.
Note: TABLE_A REB 700 million, TABLE_B 4 million and TABLE_c is located only 500 RECS
Thank you!Advantage of the fact that aggregate functions more ignore nulls, you could do something like:
SELECT a.p_id, b.p_name, c.p_desc, COUNT(CASE WHEN a.date BETWEEN TRUNC(ADD_MONTHS(LAST_DAY(sysdate),-4) + 1) AND ADD_MONTHS(LAST_DAY(TO_DATE(sysdate)),-1) AND a.m_id IS NOT NULL THEN m_id END) AS countall, COUNT(DISTINCT CASE WHEN a.date BETWEEN TRUNC(ADD_MONTHS(LAST_DAY(sysdate),-4) + 1) AND ADD_MONTHS(LAST_DAY(TO_DATE(sysdate)),-1) AND a.m_id IS NOT NULL THEN a.m_id END) AS unique_count, /* entirely possible */ SUM(CASE WHEN a.date BETWEEN TRUNC(sysdate,'YEAR') AND ADD_MONTHS(LAST_DAY(TO_DATE(sysdate)),-1) THEN a.amt_1 ELSE 0 END) AS total_amt_1, SUM(CASE WHEN A.DATE BETWEEN TRUNC(sysdate,'YEAR') AND ADD_MONTHS(LAST_DAY(TO_DATE(sysdate)),-1) THEN A.AMT_2 ELSE 0 END) AS TOTAL_AMT_2 FROM table_a a, table_b b, table_c c WHERE a.p_id = b.p_id and b.pt_id = c.pt_id GROUP BY a.p_id, b.p_name, c.p_descThe two statements inside the COUNTY box return a.m_id or NULL. A simplified test case is:
SQL> WITH t as ( 2 SELECT 1 m_id, 9 dt FROM dual UNION ALL 3 SELECT 1 m_id, 6 dt FROM dual UNION ALL 4 SELECT 2 m_id, 9 dt FROM dual UNION ALL 5 SELECT 2 m_id, 6 dt FROM dual UNION ALL 6 SELECT 1 m_id, 5 dt FROM dual UNION ALL 7 SELECT 2 m_id, 5 dt FROM dual UNION ALL 8 SELECT null m_id, 9 dt FROM dual) 9 SELECT count(CASE WHEN dt BETWEEN 6 and 9 THEN m_id end) cid, 10 count(distinct CASE WHEN dt BETWEEN 6 and 9 THEN m_id end) cdid 11 FROM t; CID CDID ---------- ---------- 4 2I'm not entirely sure that you really need the IS NOT NULL predicate a.m_id in the instructions BOX, but I left it for more security.

I have a late 2008 aluminium MacBook El Capitan 10.11.6 running. The computer came with 2 GB of ram and the instructions say that there is a maximum of 4 GB. This ceiling is still valid or if I add 8 GB?
Yes, your MacBook accepts two RAM sticks of 4 GB, 8 GB total, you'd better update the firmware Version MB51.007D.B03.

I use MozBack to the top, when I followed the instructions of the wizard a backup file on my portable hard drive. I'm back to Thunderbird I found the content of my Inbox was deleted. Sent and deleted files have not been removed. I then returned to MozBackup and followed the instructions to restore the information from my Inbox, but it didn't happen.
What I did wrong.as incredible as it may seem. MozBackup has nothing to do with Mozilla or Thunderbird. If you have any questions about mozbackup I don't really know where you're going.

Hello
Try Firefox Safe mode to see if the problem goes away. Firefox Safe mode is a troubleshooting mode that temporarily disables hardware acceleration, restores some settings and disables add-ons (extensions and themes).
If Firefox is open, you can restart Firefox Safe mode in the Help menu:
- Click the menu button
click Help
then select restart with disabled modules.
If Firefox does not work, you can start Firefox in Mode safe as follows:
- On Windows: Hold down the SHIFT key when you open the desktop Firefox or shortcut in the start menu.
- On Mac: Hold the option key during the startup of Firefox.
- On Linux: Exit Firefox, go to your Terminal and run firefox-safe-mode
(you may need to specify the installation path of Firefox for example/usr/lib/firefox)
When the Firefox Safe Mode window appears, select "start mode safe."
If the problem is not present in Firefox Safe Mode, your problem is probably caused by an extension, theme or hardware acceleration. Please follow the steps described in the section Troubleshooting extensions, themes and problems of hardware acceleration to resolve common Firefox problems to find the cause.
To exit safe mode of Firefox, simply close Firefox and wait a few seconds before you open Firefox for normal use again.
When find you what is causing your problems, please let us know. This might help others with the same problem.

I start my search early as soon as I open Firefox.

I have reset MSN as my home page and set my home page to open when I run Firefox. Guess what? When I open Firefox, start my search opens! MSN is always my page host, but despite following all the instructions to start my search, I can't get rid of it. Can someone help please!

I manually moved my profile of Thunderbird in Ubuntu 12.04 LTS to 8.1 Windows. I followed the instructions and everything settled as expected except the calendar. Not only the calendar data has not been transferred, the calendar itself does not, for example no dates & everyday of the week, etc., all the menus associated with the calendar are "grey," etc. I'd appreciate any help. TIA KellyJMorris
Calendar (aka Lightning) contains binary components, which are dependent on OS. Thus, you should not remove the add-on lightning in your add-ons Manager and install the Windows version of lightning.

If possible to uninstall your current version of Firefox to clean the Windows registry and settings in the security software.
- Do NOT remove the data personal when you uninstall your current version of Firefox, because all profile files will be deleted and you lose personal data such as bookmarks and passwords from other versions of Firefox profiles.
Delete the program folder Firefox before installing newly downloaded copy of the Firefox installer.
- (32-bit Windows) "C:\Program Files\Mozilla Firefox\"
- (Windows 64 bit) "C:\Program Files (x 86) \Mozilla.
- It is important to remove the Firefox program folder to delete all the files and make sure that there is no problem with the files that were the remains after uninstallation.
- http://KB.mozillazine.org/Uninstalling_Firefox
Your bookmarks and other personal data are stored in the Firefox profile folder and will not be affected by a uninstall and (re) install, but make sure that 'delete personal data' is NOT selected when you uninstall Firefox.
If you keep problems also create a new profile.
